The flavor and the texture are so much better than those bitter dark chocolate bars.
American chocolates (like Hershey’s) tend to taste more sour because they have more sugar and less cacao. The milk also tends to have a more butyric acid taste for some reason. Perhaps the difference is how the milk is treated, but those are trade secrets.
I was surprised the first time I bought a Hershey’s bar and it tasted a bit like vomit.
Same, my brother returned from the US and I was excited to try Hershey’s and was horrified to find it tasted like puke. The next one did too.
They all sat on the table for weeks before they got thrown away which is unheard of in our house with sweets.
Cadbury isn’t the best in the world or anything but not tasting like puke is like, up there in the list of things that make chocolate good.
butyric acid is more prevalent in US chocolate for some accident of history.
So, to non-Americans, American chocolate takes like vomit.
